provided patch for testing any changes to fsx.c

I generated some quick tests to make sure any changes to fsx.c don't have any unexpected results.

moved F_NOCACHE to a new header file to help port fsx.c

I propose the addition of a new header file, fsx.h, to help port fsx.c to other platforms. My changes compile on "Darwin Kernel Version 14.0.0" and "FreeBSD 10.1-STABLE". The biggest change is moving F_NOCACHE to the header file.

My goals were:

to keep any conditional compilation noise confined to fsx.h, instead of putting this in fsx.c
to keep the functionality of fsx.c the same as the original
avoid using conditional compilation to prevent parts of fsx.c code from compiling on other platforms

small cleanup to fsx.c

I have proposed some changes that fixes the following:

for msync(), uses MS_SYNC, instead of hard coding zero
for mmap(), uses MAP_FAILED, instead of harding coding -1
for getopt(), using -1, instead of EOF
added "y" to the getopt string -- this is already implemented but is missing from the command line args
